[header] How to draw a histogram [title] Using a ruler, draw out the basic axes. [step] These are the vertical and horizontal lines that form basic outline of the histogram. If you have trouble making the right angle where the axes meet, go ahead and cheat: use a corner of a sheet of paper! [title] Measure out the groups. <sep> (A) [step] In a histogram, the data is visualized in groups. These groups are evenly distributed, so you'll need to make set marks along your lower axis. (B) [step] Draw a triangle to the left and a circle on the right just so you have a rough outline of the groups. [title] Next, draw x-shaped triangles to represent the degrees of sides. (C) [step] A pinch or two measure out two different groups. Repeat this once you have your group squared and neat so you can then include your lines. (D) [step] Each group should include 1.011 pixels and a number (based on use of our metric chart). For example : 1.011 pixels = 4000 pixels.
Output:
A
